Management of AS has changed dramatically with the introduction of transcatheter aortic valve replacement (AVR). The shift in management of AS, combined with an aging population, may increase the cost of patients with AS in the US health care system.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec xml:lang=\"en\">\n            <jats:title>Methods and Results<\/jats:title>\n            <jats:p xml:lang=\"en\">\n              We performed a retrospective cohort study, using inpatient, carrier, and outpatient data from a 20% Medicare fee\u2010for\u2010service beneficiaries' sample from 2008 to 2019 and included beneficiaries, aged \u226565\u2009years. We identified beneficiaries with a diagnosis of AS and stratified the sample into 3 age groups: 66 to 74, 75 to 84, and \u226585\u2009years. We evaluated the crude and adjusted changes in annual Medicare payments (total and component) per beneficiary. We identified 1\u2009887\u2009340 (1.6%) Medicare beneficiaries diagnosed with AS. The average annual spending for Medicare beneficiaries with AS was $19\u2009241 in 2010 and increased annually by $301 to $23\u2009174 in 2019 (\n              <jats:italic>P<\/jats:italic>\n              &lt;0.0001). Annual Medicare payments on patients with AS increased from $2\u2009894\u2009995\u2009131 in 2010 to $4\u2009619\u2009077\u2009182 in 2019, a difference of &gt;1.7\u00a0billion dollars. Inpatient spending increased 1.1% per year, with the highest increase in patients aged \u226585\u2009years (1.9%). The percentage of beneficiaries undergoing surgical AVR decreased from 3.7% to 1.6%, and annual spending on surgical AVR decreased an average of 7.2% per year. The percentage of beneficiaries undergoing transcatheter AVR increased from 0% in 2010 to 3.8% in 2019, and annual spending for transcatheter AVR increased by 458.7% per year.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec xml:lang=\"en\">\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p xml:lang=\"en\">Although average annual Medicare spending per beneficiary modestly increased over the study period, the increase in the prevalence of AS and the proportion of beneficiaries undergoing (transcatheter) interventions for AS led to a substantial increase in overall Medicare spending among patients with AS.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1161\/jaha.122.026102","type":"journal-article","created":{"date-parts":[[2022,7,5]],"date-time":"2022-07-05T11:17:00Z","timestamp":1657019820000},"update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":6,"title":["Trends in Medicare Payments for Beneficiaries With Aortic Stenosis"],"prefix":"10.1161","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8890-6111","authenticated-orcid":false,"given":"Pieter A.
